Patented Jan. 14, 1930 UNITED STATES PATENT OFFICE srnnve com Application led cto"ber 26, 1927. Serial No. 228,950.

My invention relates to improvements in vspring covers, and it consists in the combinations, constructions, and arrangement-s hereinafter described and claimed.

An object of my invention is to provide a spring cover for collapsible tubes, in which the cover is instantly returned to cover the mouth of the tube as soon as the handle of the cover is released.

A further object of my inventionis to provide a device of the type described in which the entire device is supported by a cap that may be threaded upon the end of the tube to take the place of the usual cap.

Other objects and advantages will appear in the following specification, and the novel features of my invention will be particularly pointed out in the appended claim.

My invention is illustrated in the accompanying drawing forming a part of this application, in which:

Figure 1 isa section along the line 1-1 of Figure 5;

Figure 2 is a section along the line 2-2 of Figure 1;

Figure 3 1s a perspective view of the spring;

Figure 4 isa development of the cover and the handle; and l Figure 5 is a top plan view ofithe device. In carrying out my invention I make use of a collapsible tube 1 having a mouth portion 2 and athreaded stem 3. A cap 4 is threaded upon the tubular member 3, and has a pair of lugs 5 which straddle a handle 6. The 'development of the handle is shown in Figure 4. The handle has ends 7 with openings 8 therein for receiving a pintle 9. This pintle is passed through the lugs 5 and 4o supports a s rmg 10, shown in Figure 3.

Figure 4 s ows the handle 6 ascarryin a cover portion 11. The periphery of t is cover may be bent downwardly along'the dotted line 12 shown in Figure 4 to grip a resilient stoppe'i` 13, which is shown to be hemisEherically in shape in Figure 1. The cap 4 as a seat14 for receiving the resilient member 13.

The s rin 10 has one end 15 secured to the han le 6 y a clipl, while its other end is turned at right-angles as at 17, and bears 'against one of the lugs 5, see Fi res 2 and 5.

From the foregoing descriptlon of the va rious parts of the devlce, the operation thereof may be readily understood. The spring 10 urges the cover into closed position. T e cover is opened against the tension'of the spring when the handle 6 is depressed. IAs soon as the handle is released the cover will instantly swing into closed position, thus sealing the contents of the tube 1.

The cap 4 may be screwed upon the tubular member 3 and takes the place of the usual cap, provided with the tube. With the device it 1s unnecessary for the o erator to remove the standard cap and rep ace it each time he wishes to remove a portion of the contents from the tube. A mere pressure on the handle 6 opens the mouth 2 and permits the contents to be squeezed therethrough. When the tube is set down, the cover 11 instantly swings into closed position and hermetically seals the device. l The device is extremely simple in constru.

tion9 and provides a self-supporting unit that 11'5.

my be screwed onto a standard collapsible tu e.

Although l have shown and described one embodiment of my invention, it is to be understood that the same is susceptible of various changes and I reservethe right to employ such changes as may come within the scope of the appended claim.

I claim: A spring cover comprising a ca having a bore therethrough which terminates at the top in a rounded cavity, said cap having a threaded portion adapted'to be`screw'ed onto a receptacle, a lever' pivotally carried by said cap and having ,a resilient rounded stopper receivable in said rounded cavity, and spring means for seating said stopper when said lever is released.
